Collapsing Glomerulopathy (CG) is a rare entity presenting as nephrotic syndrome and rapidly progressive renal
deterioration. It has been first identified among African-American patients and subsequently dubbed HIV-associated nephropathy after a number of patients with HIV were found to have CG. It has re-emerged recently among patients with COVID-19. To our knowledge, this is the first case of primary collapsing glomerulopathy in the country to be published.
The case is a 36-year-old Filipino female admitted due to bipedal edema which started 2 weeks post-partum. She
has no comorbidities and social history was negative for illicit drug use. Initial work up showed hypoalbuminemia and diffuse hepatic disease on ultrasound. She was referred to a gastroenterologist where albumin infusion and paracentesis was done but with no improvement. She developed anasarca and was admitted. Paracentesis obtained minimal ascitic fluid. Serum ascites albumin gradient was low and baseline laboratories showed high creatinine, hypoalbuminemia, and albuminuria. 24-hour urine protein was 11 grams, ANA and anti-DsDNA were negative and c3 and c4 levels were normal. Hepatitis profile was negative for infection. Abdominal CT scan revealed multiple hypoenhancing lesions. Tumor markers CA-125, CA 19-9 and CA 15-3 were high. Breast ultrasound showed simple breast cyst. Gynecology consult was called where pap smear was negative for atypical cells. Surgery service recommended monitoring for the pancreatic and breast lesions. Kidney biopsy was delayed due to new onset bacterial pneumonia. COVID-19 RT-PCR test was negative. Patient was discharged improved with no edema. On follow up, the kidney biopsy result came out to be collapsing glomerulopathy. HIV test was then done and was negative. Bipedal edema and albuminuria recurred. She was started on tacrolimus. She has been on regular follow up and currently has no edema, no proteinuria and normal creatinine level.
This is an interesting case as the primary glomerular disease has been masked by the earlier laboratory findings
which led us to think of liver disease then a paraneoplastic nephrotic syndrome. Ultimately, the renal biopsy revealed the diagnosis. This serves as an index case for primary collapsing glomerulopathy in a Filipino patient on remission after being treated with tacrolimus.

Clinical blood transfusion is one of the most important supportive therapy for patients with tumor. The blood transfusion has dual effects for patients with tumor. First, blood transfusion can rectify anemia and improve oxygen saturation, accelerate oxidation and necrosis for tumor cells; the second, blood transfusion can induce immunosuppression, tumor recurrence and postoperative infection for tumor patients. Filtering white blood cells (WBC) before blood transfusion can decrease the incidence of the adverse reactions. The rational perioperative autotransfusion for patients with tumors is focus to which the world medical sciences pay close attention. In this article, the support effect of blood transfusion for treatment of tumor patients, blood transfusion and immunosuppression, blood transfusion and postoperative infection and relapse of tumor patients, depleted leukocyte blood transfusion and autologous transfusion of tumor patients are reviewed.

ABSTRACT
Methanolic extract from the leaves of Acanthus ilicifolius L. (A. ilicifolius L.) is a potent inhibitor of
Candida albicans (C. albicans) growth and anti-inflammatory. C. albicans causes oral candidiasis in
immunosuppressive condition. Mitogen-activated protein kinase (MAPK) signalling via p38 appears
to discriminate between yeast and hyphal cells of C. albicans. Activation of p38 MAPK by hyphae
results in the upregulation of proinflammatory cytokines. The p38 MAPK activation is known to
impair corticosteroid action. The research was conducted to investigate the effect of methanolic
extract A. ilicifolius L. treatment of oral candidiasis with the immunosuppressive condition through
enhancement of p38 MAPK expression in the epithelial cells. Immunosuppressed conditions
were obtained when 16 healthy male Rattus norvergicus (Wistar) was given oral administration
of dexamethasone and tetracycline for 14 days and induced with C. albicans (ATCC-10231)
1 McFarland. The subjects were divided into four groups (n = 4/group): immunosuppression
(IS), immunosuppression with oral candidiasis without treatment (ISC), immunosuppression
with oral candidiasis and nystatin treatment (ISC+N), and immunosuppression with oral
candidiasis and A. ilicifolius L. treatment (ISC+AI), and were treated for 14 days. Later, the rats
were euthanised, and their tongue were biopsied. The p38 MAPK expression was subjected to
immunohistochemical examination, observed under a microscope (400× magnification) and
statistically analysed (one-way ANOVA, LSD-test, p < 0.05). The p38 MAPK expression of
ISC+AI (36.05 ± 1.54) was higher than IS (26 ± 2.32), ISC (26.4 ± 3.71), IS+N (34.2 ± 0.99).
Significant differences existed between ISC+AI and ISC+N to IS and ISC (p < 0.05). No significant
differences were present between IS and ISC; ISC+AI and ISC+N (p > 0.05). Therefore, this treatment
could enhance p38 MAPK expression in oral candidiasis with the immunosuppressed condition.

OBJECTIVES:
To study the association between paroxysmal nocturnal hemoglobinuria (PNH) clone and immunosuppressive therapy (IST) in children with severe aplastic anemia (SAA).
METHODS:
A retrospective analysis was performed on the medical data of 151 children with SAA who were admitted and received IST from January 2012 to May 2020. According to the status of PNH clone, these children were divided into a negative PNH clone group (n=135) and a positive PNH clone group (n=16). Propensity score matching was used to balance the confounding factors, and the impact of PNH clone on the therapeutic effect of IST was analyzed.
RESULTS:
The children with positive PNH clone accounted for 10.6% (16/151), and the median granulocyte clone size was 1.8%. The children with positive PNH clone had an older age and a higher reticulocyte count at diagnosis (P<0.05). After propensity score matching, there were no significant differences in baseline features between the negative PNH clone and positive PNH clone groups (P>0.05). The positive PNH clone group had a significantly lower overall response rate than the negative PNH clone group at 6, 12, and 24 months after IST (P<0.05). The evolution of PNH clone was heterogeneous after IST, and the children with PNH clone showed an increase in the 3-year cumulative incidence rate of aplastic anemia-PNH syndrome (P<0.05).
CONCLUSIONS
SAA children with positive PNH clone at diagnosis tend to have poor response to IST and are more likely to develop aplastic anemia-PNH syndrome.

Disseminated superficial actinic porokeratosis, a variant of porokeratosis, is an uncommon, hereditary or acquired keratinization disorder. It is characterized histologically by cornoid lamella and clinically by central atrophy with elevated borders. Porokeratosis lesions may be triggered by UV light exposure, infection, hematopoietic malignancies, or immunosuppression, but are rarely reported associated with malignancies of visceral organs. We herein report an unusual case of a patient with colon cancer who noted sudden exacerbation of a previously unrecognized disseminated superficial actinic porokeratosis lesion after being treated with chemotherapy.

Posttransplant lymphoproliferative disorder (PTLD) are among the most serious and potentially fatal complications of chronic immunosuppression in organ transplant recipient and also the most common malignancies, accounting for 21 percent of all malignancies in organ transplants versus 5 percent of malignancies in the general population. PTLD is associated with immunosuppression and Epstein Barr virus (EBV). Treatment modality of PTLD includes antiviral agent, interferon, intensive chemotherapy and monoclonal antibody. Choice of treatment modality depends on clinical presentation of PTLD. We report here a case of PTLD involving liver and renal allograft treated with rituximab.

9.Targeting Foxp3+ regulatory T cells-related immunosuppression for cancer immunotherapy.
Chinese Medical Journal 2010;123(22):3334-3342
OBJECTIVETo review the current research into Foxp3(+) regulatory T cells (Treg) cell surface molecules, plasticity of Treg cells and mechanisms of Treg cell suppression and to explore the possibilities to interfere in Treg cell suppression of anti-tumor immunity.
DATA SOURCESA literature search of all English articles was performed on the online electronic PubMed database dated 1995 to 2010. The keywords searched included: CD4(+)CD25(+)Foxp3(+) regulatory T lymphocytes, cancer, and immunotherapy. After finding relevant articles within these search limits, a manual search was conducted through the references from these articles.
STUDY SELECTIONArticles regarding the role of Treg cells in tumor immunity and the utility of Treg cells in tumor immunotherapy.
RESULTSThe results show that significant numbers of Treg cells are found in many tumors and it has been shown that the number of tumor infiltrating Treg cells correlates with adverse clinic outcomes. Treg cells are emerging as a key component of acquired tolerance to tumors.
CONCLUSIONSSeveral mechanisms of immunosuppression can be mediated by Treg cell function. Distinct immunosuppressive molecules expressed by Treg cells or diverse molecules related to Treg induction or migration represent potential drug targets for cancer immunotherapy.

10.Immunosuppressive Treatment of Non-infectious Uveitis: History and Current Choices.
Chinese Medical Sciences Journal 2017;32(1):48-61
Non-infectious uveitis is one of the leading causes of preventable blindness worldwide. Long-term immunosuppressive treatment is generally required to achieve durable control of inflammation in posterior and panuveitis. Although systemic corticosteroids have been the gold standard of immunosup- pressive treatment for uveitis since first introduced in 1950s, its side effects of long-term use often warrant an adjuvant treatment to reduce the dosage/duration of corticosteroids needed to maintain disease control. Conventional immunosuppressive drugs, classified into alkylating agent, antimetabolites and T cell inhibitors, have been widely used as corticosteroid-sparing agents, each with characteristic safety/tolerance profiles on different uveitis entities. Recently, biologic agents, which target specific molecules in immunopathogenesis of uveitis, have gained great interest as alternative treatments for refractory uveitis based on their favorable safety and effectiveness in a variety of uveitis entities. However, lack of large randomized controlled clinical trials, concerns about efficacy and safety of long-term usage, and economic burden are limiting the use of biologics in non-infectious uveitis. Local administration of immunosuppressive drugs (from corticosteroids to biologics) through intraocular drug delivery systems represent another direction for drug development and is now under intense investigation, but more evidences are needed to support their use as regular alternative treatments for uveitis. With the numerous choices belonging to different treatment modalities (conventional immunosuppressive agents, biologics and local drug delivery systems) on hand, the practice patterns have been reported to vary greatly from center to center. Factors influence uveitis specialists' choices of immunosuppressive agents may be complex and may include personal familiarity, treatment availability, safety/tolerability, effectiveness, patient compliance, cost concerns and suggestions from related specialists such as rheumatologists and pediatricians. The focus of this review is to provide an overview of each treatment modality on safety/tolerability and effectiveness, which are believed to be the two most important factors affecting treatment decision making.
